Any sense of how the
Cayman S
Big Reds compare to the Brembo? Does
porsche
in fact use Brembo and just re-label?
The brakes are indeed Brembo sets with
Porsche
logo, so I believe.
They work pretty good.

the brake that the
cayman
has is a brembo.
if you took the wheels off, u can see there is an engraving of brembo on the caliper
brakes compared to aftermarket
Actually, I believe it's a bit more complicated than that. Prior to the Boxster being introduced in the mid-1990's Porsche worked with Brembo to design new brake calipers that could be cast as a single piece of alloy (lighter, cheaper, lower failure rate), rather than the Brembo calipers that were used up to that point which were cast in two halves and then bolted together (you can see the large bolt heads on either side of these calipers.. e.g. 930, 951, 964, 968). The new one-piece caliper design (called "Monobloc" calipers in the Porsche marketing-speak), are/were subject to SHARED patent: 50% Brembo and 50% Porsche. SO... even though Brembo manufactures the complete brake assembly and ships them to Porsche ready to go on the cars as they come down the production line, they are not just re-labeled off the shelf Brembo parts. They are Porsche parts, made to Porsche specs, manufactured by Brembo. Monobloc calipers are used on all 986, 996, 987, 997 cars.
If you look at aftermarket brake kits, you can see that some of them have bolts holding the two halves of the calipers together. I’m not an engineer, so I won't pass judgment as to whether the monobloc design is better or worse, but it is different. At a minimum, I would presume the monobloc design could be lighter since there is no need for steel bolts passing through the alloy structure.

Very interesting. Thanks.
This is interesting, thanks....
My yellow
PCCB
calipers have Brembo stamped on them.
Brembo has recently released their own "big brake kit" or in this case I should say "kits" for the
Cayman
.
For a base line, the stock OEM brakes on the
Cayman
(&
Boxster S
for that matter) are based on one piece 318x28mm front rotors, and 299x24mm rear, again one piece rotors. In English units, these are roughly 12.51" x 1.1" front heat sinks, assisted by 11.8" x .94" rears, or roughly the equivalent of a stock Mazda Rx8 OEM brake set up.
The Brembo BBK comes in three flavors, first a 355mm x 32mm using 4 piston calipers; a 380mm x32mm (15") 4 piston calipers; and finally a 380mm x 32mm using 6 piston calipers.
Other alternatives may be out there also using stock OEM Porshe parts off, say the
GT3
. I don't off hand have the size of the
GT3
(non-
PCCB
) rotors and components, but I believe they would at least be of 32mm thickness (maybe more), and I think the
GT3
uses a 6 piston caliper. I think the non-
PCCB
GT3
brake rotors are also of a one piece design, as distinguished from say the 993tt brakes which uses a two piece 322x32mm rotor.
There may be other alternatives coming on line with other suppliers out there as well. What I'd like to know is how similar are the
Cayman S
brakes and fitment to say, any thing built for the 200x-2005
Boxster S
? There seems to be a lot of existing brake kit stuff out there for the
Boxster S
.
HTH some one else out there ~ Cheers
I'm sure as the
Cayman
ages other companies will join the fray. Brembo's certainly there and Willwood and AP Racing shouldn't be far behind.
I don't think it is necessary to upgrade to larger brakes. The standard brakes on the
Cayman
are good enough I believe even after adding more HP. When I supercharged my
M3
all I did was upgrade the tires, rotors, and pads. As we all know, it is the tires that are most responsible for a good brake. Tires not rotors are what connects the car to the road. If you don't have the right tires your 6 piston big brake kit won't do you much good. And unless you take your car to the track I don't see a good reason unless for aesthetics to upgrade to a big brake kit. Big rotors require more heat and you won't get that much action on the street.
Are the rotors and pads also from Brembo fresh from the factory? All the replacement "OEM" rotors and pads I've seen were from Zimmermann and Textor.
